LDAP High-Availability Testing Wednesday 10pm

We are upgrading our [LDAP infrastructure](https://iris.eecs.berkeley.edu/news/10933-department-ldap-upgrade-thu-jan) to replace an old server with a new machine. This server is a backup node which should take over the role of the LDAP server if the primary server fails. In order to ensure the new server is performing as expected, we will be simulating a failure of the primary node at 10pm on Wednesday, June 17th. The backup node should take over within 5 seconds. If all goes as planned, we will then bring the primary back up and call it a successful test.

During this testing, there will be brief (~5 second) interruptions in LDAP service. This will occur at least twice but possibly more if the first test is unsuccessful. During those brief intervals, anyone whose timing is especially good might notice trouble logging into any application that uses LDAP.

All testing will be over by 10:30pm at the latest, but probably much sooner.
